RAILWAY-TRACK CONSTRUCTION.

Specification of Letters Patent.

Application filed January 28, 1910.

Patented May 3, 1910. Serial No. 540,576.

T 0 all whom it may concern:

Be it known that I, JOSEPH IV. BLOWER, i a citizen of the United States,residingat Columbus, in the county of Franklin and State of Ohio, haveinvented certain new and useful Improvements in Railway-TrackConstruction, of which the following is a specification.

My invention relates to the improvement of railway track constructionand has particular relation to the improvement of the construction setforth in my pending application for Letters Patent Serial Number 537,134, filed January 10th, 1910.

The objects of my present invention are to provide an improved railwaytrack construction which will permit 01: the use of track rail sectionsas ties; to so form the terminal portions of the ties as to obviate atendency of the track moving laterally and admit of the bed beneath thetie terminals being so tamped as to resist clownward or outward movementof the ties; to provide improved means for producing track railretaining projections on the ties and to produce other improvements thecletails of which will be more fully pointed out hereinafter. Theseobjects I accomplish in the manner illustrated in the accompanyingdrawing, in which Figure 1 is a transverse section of a railway trackshowing one of my improved ties in elevation, Fig. 2 is an enlarged endview of one of the ties showing a portion of a track rail in elevationthereon, Fig. 3 is an enlarged sectional view on line 00:c of Fig. l,with the track rail removed, and, Fig. a is a detail view in elevationof one of the locking pins which I employ.

Similar numerals refer to similar parts throughout the several views.

1 represents one of my improved track rail supporting ties, which is asection of an ordinary T-track rail of the desired length. The tie thusformed has its end portions bent upward, the upturned terminal membersbeing indicated at 1*. In order to provide for the retention of thetrack rails upon the ties, I produce in the ball or tread portion 2 ofthe tie rail toward each end of the latter, a tapering recess 3, whichresults in the production of an inwardly projecting bracket tongue 1,the under face of which is inclined. The recess 3 is produced by asuitable tool which is forced or driven into the body of the rail 1ball. At a proper distance on the inner side of each of the tongues 4t,I form through the ball of the tie rail a vertical opening 2 which atits lower end communicates with an opening 5 in the web 5 of the tierail.

6 represent the track rails which are of the usual T-form in crosssection. These rails are designed to be so laid and supported upon thetie rails as to cause the recesses 3 in the balls of said tie rails, toreceive the outer base flanges of the track rails, as shown more clearlyin Fig. l of the drawing. The inner base flanges of the track rails havetheir upper sides engaged by the inwardly projecting heads '7' oflocking pins 7 one of which is inserted through each of the holes 2 Eachof these pins has its stem or body portion split centrally from itslower end to a point near the center of its length, with the result thatwhen the members 7 of the pin come into contact with the web 5 of thetie rail at the bottom of the opening 5 said members will be spreadoutward on opposite sides of the web, thus locking the pin againstwithdrawal.

In my said former application, I have shown and described ties formed ofsections of track rails, in-whieh the ends of the ball of the tie railare split longitudinally and turned upward and inward to form track railengaging tongues of the character shown at 4 in my present invention. Itis obvious that by forming said tongues by the bending operationdescribed, the metal is stretched and therefore slightly weakened. Bythe method herein described of forming the tongues, it is obvious thatthe strength of the latter is in no way weakened or impaired. It willalso be observed that owing to the fact that I have bent the ends of theties upward producing the inclined terminal members 1 space is providedbeneath the tie ends which may be filled with gravel or other materialforming the road bed and such filling tamped to form a hard andsubstantial bearing for the upturned terminal members of the ties. Bythus filling and tamping the material beneath these upturned tie ends,it is obvious that the supporting bed of the road will ofier aresistance to the track which will tend to prevent any undesirablelateral movement of the track in its bed.

From the foregoing description, it will be seen that simple andeflicient means are herein provided for accomplishing the objects of theinvention, but while the elements shown and described are well adaptedto serve the purposes for which they are intended, it is to beunderstood that the invention is not limited to the precise constructionset forth, but includes within its purview such changes as may be madewithin the scope of the appended claims.

hat I claim, is-

1. In a railway track construction the combination with ties formed ofsections of track rails, the ball of each of said tie rails havingformed therein on each side of the center of the length of the tie ahorizontal recess of track rails mounted upon said ties and having theiroutwardly projecting base portions engaging said tie recesses, and meansfor locking the inner base flanges of the track rails in connection withthe tie.

2. In a railway track construction, the

combination with ties each comprising a body formed of a section oftrack rail, the terminal members of which are inclined upward and theupper side of which is formed on each side of the center of its length,with a horizontal recess as described, of track rails mounted upon saidties, the outer flanges of said rails engaging said tie recesses, andmeans for locking the inner flanges of said rails in connection withsaid ties.

In testin'ion whereof I affix my signature in presence of two witnesses.
